SLDE DOOR FOR BOX. CARS.

Application filed March l, 1926. Serial No.` 91,588.

This invention relates to doors and particularly to metal side doors for use on box cars. The invention involves certain detailed improvements over the construction disclosed in my copending application Serial no. 725,653 sled July 12, 1924.

rlhe present invention aims to provide an improved arrangement for securing the vertical stiffener bars to the front and reary edges of the door whereby the operation of assembling the door and stil'ener bars is simplified and cheapened and the resulting construction rendered very strong and durable. l

The invention andthe numerous advantages thereof will be more fully understood from the following specification and the accompanying drawings, forming a part thereof, and in which:

Fig. l is a partial elevation of the side of a box car having a door constructed according to' the present invention;

Fig. 2 is a horizontal sect-ion partly broken away, on the line 2 2 of Fig. 1;

Fig. 3 is a partial vertical section through one of the horizontal corrugations of the door and taken on line 3-3 of Fig. 1;

Fig. l is a partial sectional view similar to one end of Fig. 2 and showing a slightly modified arrangement; and

Fig. 5 is a horizontal section similar to Fig. 2 showing another modified arrangement.

Referring to the drawings by the reference characters thereon, 10 indicates part of a box car body to which the improved door, generally indicated bythe numeral 1l, is applied. rlhe door may be slidably suported on the car in any suitable manner, as by pairs of rollers 12 adapted to travelbn a track 13, the upper edge of the door being held in place by a bar 1K1 beneath which the door may slide. i l

As in the case of my said prior application, the door is preferably formed, of a plurality of metal plates 11A secured together at their meeting edges in such a way as to form horizontal ribs or corrugations 11B eX- tending across the door. yll`hese corrug'ations are produced by bending the edge portions 11C of adjacent plates outwardly at 1 substantially a right angle to the plane of the plates 11A, and then bending the inar-4 ginal portions 11D of the plates into a plane substantially parallel to the plane of the plates. rll`he portions 11D are then overlapped and riveted together as at 11E. 'ihere'is thus produced a corrugation `at the meeting edges of each two adjacent plates 11A. That portion of the corrugations formed bythe overlapping edges 11D of the plates, will hereinafter be termed the top of the corrugations. 1n the present arrangementathe corrugations 11B preferably extend inwardly insteadof outwardly as in my sald prior application.

Referring to Figs. 1, 2, 3 and 4, l arrange an angle'r'nember 15 adjacent the end of each corrugation. Each of these angle members has one of its legs 15A riveted to the top of the corrugation. r1`he leg 15A niay be, and preferably is, riveted to the inner surface of the top of the corrugation, as in Figs. 2 and 3, although it may if desired be riveted to the outer surface of the top as shown iu Fig. 4. 'llhe outer leg 15B of each angle member 15 extends transversely of the end vof the corrugation and vertically extending stidener bars 16 and 16 are riveted to each of said legs 15B. The stiffener bar 16 is preferably provided with a flange 16A which overlies and contacts with and is riveted to the plane surfaces of the plates 11A between the corrugations 11B. The stiifener bar at the front of the door is preferably in the form of a Z bar having a fiange 16B for cooperating with the door-post, as described in my former application7 and the stiffener bar at the rear of the door is provided with a distorted flange 16C, the purpose of which is also fully set forth in said prior application.

1n the form illustrated in Fig. 5, the stiffener bars 20 and 20 are substantially the same as the bars 16 already described, and are provided with flanges 20A, 20B and 20C which perform the same functions as the corresponding flanges 16A, 16B and 16C. fn this form, however, the bars 20 are provided with supplemental flanges 20D, preferably integral therewith, and which extend the full length of the bars 20. The flanges 20 overlie and are secured by riveting to the tops of the corrugations 11B. The function of the planes 20D is therefore analogous to that of the angle members 15.

rllhe construction described provides a door which is comparatively light and cheap to manufacture and which is very strong and rigid and durable, andcapable of withtiti doors are subjected in use.
